This showstopping helix hoop features a 4mm x 4mm heart set with a trio of 1mm, cubic zirconia crystals. The clear stones add plenty of sparkle to this 9ct yellow gold earring. The hoop has a 7mm diameter, but the hinged pin fastening makes fitting much easier, despite its smaller size. It weighs just 0.2 grams and carries a 375 metal stamp.
